Why is My Gas Furnace Blowing Cold Air?

Heating

As the seasons change, the more you feel the cool air gusting outside. And … in your home? If your gas furnace is blowing cold air and putting a chill to your Baltimore home, it’s time to contact Quality Refrigeration. Once in a while the loss of warm air from your gas furnace results in a large repair, but a lot of time it can be an easy fix. Here are some of the main reasons your gas furnace may be blowing cold air instead of keeping your home toasty.

Your furnace might be overheating

If you haven’t had routine maintenance completed on your gas furnace recently and you’ve neglected to replace your air filter, either could indicate why your furnace is blowing cold air. A dirty air filter can block air from flowing freely through your furnace. If this occurs, the furnace may overheat and shut down its burner.

Your pilot light may have gone out

Sometimes a lack of warm air from your gas furnace can be attributed to something as simple as a pilot light that’s gone out. It’s possible, especially with older furnaces, for a draft to put out a pilot light. Other causes of an extinguished pilot light are defective gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can cause issues for your gas furnace, so can other furnace components if they aren’t properly cleaned. A dirty gas burner or flame sensor could cause your furnace to struggle to stay lit and leave you in the cold.

Your ducts may not be properly sealed

If your ducts aren’t properly sealed or if they have any cracks or holes in them, you could be losing a lot of heated air before it even reaches the vents throughout the home.
